A clean example: a 10 kg object at 10 m/s neatly demonstrates the KE = ½mv² formula with a result of 500 J.
Frequently asked questions
- Why does speed have a larger effect than mass?
- Because speed is squared. Doubling mass doubles KE; doubling speed quadruples it.
- How do I convert km/h to m/s?
- Divide by 3.6. For example, 90 km/h = 25 m/s.
